[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] The present invention provides a clothes dryer, which aims to solve the problem of low drying efficiency of clothes dryers in the prior art when drying private clothes. Figures 1 to 14The clothes dryer comprises: a clothes drying drum 1, which rotates along its own central axis; a space divider 2, which is arranged in the clothes drying drum 1 along the central axis and divides the clothes drying drum 1 into a first drying chamber 11 and a second drying chamber 12; an air outlet assembly 3, which is arranged at one end of the axis along the central axis of the clothes drying drum 1, and the air outlet assembly 3 is provided with a first air outlet 324 and a second air outlet 325 respectively connected to the first drying chamber 11 and the second drying chamber 12; a return air assembly 4, which is arranged at the other end of the clothes drying drum 1 opposite to the air outlet assembly 3, and the return air assembly 4 is provided with a first return air outlet 424 and a second return air outlet 425 respectively connected to the first drying chamber 11 and the second drying chamber 12. The clothes drying drum 1 is the core component of the clothes dryer. The interior of the clothes drying drum 1 is used to place clothes to be dried. It is supported by a drum frame 13 to maintain the roundness of the drum. The clothes drying drum 1 can rotate along its own central axis, and can be driven to rotate by a motor. The rotation scheme is a prior art and will not be described here. As the dryer 1 rotates, the clothes roll under gravity, which helps to evenly distribute the drying airflow and dry the clothes quickly and efficiently. The space divider 2 is a component used to divide the internal space of the dryer 1 into two independent drying chambers, that is, to separate the first drying chamber 11 and the second drying chamber 12. The function of this divider is to allow the internal space of the dryer to perform two different drying operations at the same time, such as drying different types of clothes at the same time, such as private clothes and ordinary clothes, or to efficiently classify and dry the clothes according to the amount and fabric type. The air outlet component 3 is located at one end of the dryer 1. The air outlet component 3 is responsible for blowing the drying airflow into the dryer 1. The air outlet component 3 is provided with two first air outlets 324 and second air outlets 325 that are connected to the first drying chamber 11 and the second drying chamber 12 respectively. That is, hot air can enter different drying areas through different air outlets to ensure that the clothes in each area can be dried evenly. The return air component 4 is arranged at the other end of the dryer 1 and serves to draw back the air inside the dryer 1. The return air assembly 4 is equipped with a first return air vent 424 and a second return air vent 426, respectively connecting the first drying chamber 11 and the second drying chamber 12. The return air vents allow air to circulate within the dryer drum 1, accelerating the drying process and improving the dryer's thermal efficiency. The two sets of air outlets and return air vents allow the independent flow of drying air in the two chambers, allowing clothes in different zones to be dried independently. During use, the user can adjust or remove the dryer's divider as needed, choosing to use both chambers simultaneously or only one. For example, if drying delicate items, the user can choose to dry only the second drying chamber 12, while leaving regular clothes in the first drying chamber 11. This zoned drying design effectively prevents cross-contamination between clothes and improves drying efficiency. Furthermore, the dryer is equipped with an intelligent temperature control system that adjusts the temperature and air speed based on real-time data from the humidity sensor to ensure a balanced drying time for clothes in each zone, thereby achieving energy-saving and efficient drying.Through the scheme of the embodiment of the present application, the clothes dryer can complete the drying of different types of clothes in the same cycle, greatly improving the drying efficiency, and also meeting the special needs of the family for privacy clothes, avoiding the waste of time and energy due to the separate drying of privacy clothes and ordinary clothes in the traditional clothes dryer.

[0041] Compared with the prior art, in the technical scheme of the present application, a space dividing piece is arranged in the drying drum 1 of the clothes dryer to obtain two independent drying cavities, and then an air outlet and an air return are arranged at the two ends of the two drying cavities, so that the clothes in the two drying cavities can be dried separately, thereby enabling the user to dry more privacy clothes at one time and improving the drying efficiency of the clothes dryer.

[0042] In an embodiment, referring to Figures 1 to 4 The clothes dryer of the present application further comprises a first air fan, a second air fan and a drying and dehumidifying module 71 circulation air path, the circulation air path is arranged outside the drying drum 1, the first air outlet 324 and the first air return 424 are connected to the first air fan and the drying and dehumidifying module 71 through the circulation air path, and the second air outlet 325 and the second air return 425 are connected to the second air fan and the drying and dehumidifying module 71 through the circulation air path. Figure 4 For example, Figure 4 The circulation air fan 72 in the drying air flow circulation pipeline of the clothes dryer body 81 shown in the embodiment can be the first air fan or the second air fan. The first air fan or the second air fan is arranged inside the clothes dryer and used to push the drying air flow, helping the hot drying air flow to circulate in the first drying cavity 11 and the second drying cavity 12 in the drying drum 1. The specific arrangement of the circulation pipeline of the first air fan and the second air fan is not described herein. The first air fan is mainly responsible for pushing the drying air flow in the first drying cavity 11, and the second air fan is mainly responsible for pushing the drying air flow in the second drying cavity 12. The control program of the clothes dryer can more accurately control the air flow rate of each cavity by controlling the two air fans respectively, thereby optimizing the drying effect. Figure 4Air circulates counterclockwise in the drying air circulation duct. The drying and dehumidifying module 71 is located at the front of the circulating fan 72 along the airflow circulation direction. The front of the drying and dehumidifying module 71 is connected to the return air duct 74, and the rear is connected to the outlet air duct 75. The function of the drying and dehumidifying module 71 is to remove moisture from the return air from the return air duct 74 and regulate the temperature of the drying air to ensure that moisture is discharged promptly, thereby accelerating the drying process. Temperature control ensures that drying efficiency is maintained while preventing damage to the clothing. During use, the drying and dehumidifying module 71 includes components such as a heater, a condenser, and a dehumidifier. The circulating air circuit is a system that plans and guides the air flow path within the dryer. In this embodiment, the circulating air circuit is located externally to the drying drum 1 and is connected by pipes to the first air outlet 324, the first return air outlet 424, the second air outlet 325, the second return air outlet 425, the first fan, the second fan, and the drying and dehumidifying module 71. Through a circulating air path, the first air outlet, first drying chamber 11, first return air outlet 424, drying and dehumidifying module 71 are connected to the first fan to form one circulation path. The second air outlet, second drying chamber 12, second return air outlet 425, drying and dehumidifying module 71 are connected to the first fan to form another circulating air path. Accordingly, each of the two circulating air paths also includes its own return air duct 74 and outlet air duct 75, the specific layout of which is not detailed here. The dryer uses two independent air circulation loops to control the air flow and dehumidification of the two drying chambers, preventing hot air from interfering with each other in the different drying chambers and achieving more uniform and efficient drying of clothes in each drying chamber.

[0043] In one embodiment, referring to Figures 5 to 8 The air outlet assembly 3 includes an inner air outlet structure 32, which is provided with a first air outlet interlayer 326, a second air outlet interlayer 327, and a second air outlet duct 328. The second air outlet duct 328 connects the second air outlet 325 and the second air outlet interlayer 327. The first air outlet 324 is connected to the first air outlet interlayer 326. The first air outlet interlayer 326 and the second air outlet interlayer 327 are used to input airflow to their respective connected air outlets. The first air outlet interlayer 326 and the second air outlet interlayer 327 are components of the air flow channel, respectively connected to the first air outlet 324 and the second air outlet 325 of the clothes drying drum 1, and are used to input airflow to their respective air outlets. The second air outlet interlayer 327 and the second air outlet 325 are connected via the second air outlet duct 328. The air outlet assembly 3 includes an air outlet inner structure 32. The so-called air outlet inner structure 32 is the air outlet interlayer. Its function is to separate the air flow through the structural components to ensure that the drying air flows of different circulation paths are effectively distributed and flowed without interfering with each other, thereby improving the drying efficiency. Figures 5 to 8For example, the air outlet inner structure 32 is provided with a first air outlet guide plate 321, a second air outlet guide plate 322, and a third air outlet guide plate 323. A first air outlet 324 and a second air outlet 325 are arranged on the first air outlet guide plate 321. The separation of the three guide plates creates a first air outlet interlayer 326 between the first air outlet guide plate 321 and the second air outlet guide plate 322, and a second air outlet interlayer 327 between the second air outlet guide plate 322 and the third air outlet guide plate 323. A second air outlet duct 328 passes through the first and second air outlet guide plates 321 and 322, connecting the second air outlet 325 and the second air outlet interlayer 327, thus separating the two drying gas circulation paths within the air outlet assembly 3. By providing the first and second air outlet interlayers 326 and 327, the dryer can better separate the gas flow, ensuring that the drying airflow is distributed to different drying chambers as needed. The design of the second air outlet duct 328 optimizes airflow guidance, allowing hot air to be precisely directed from the second air outlet interlayer 327 to the second air outlet port 325. The first air outlet interlayer 326 and the second air outlet interlayer 327 are arranged within the same outlet inner structure 32 via three plate structures and the second air outlet duct 328. This prevents airflow interference within each interlayer and reduces the thickness of the outlet inner structure 32, facilitating a reduction in the overall design size of the dryer and lowering the manufacturing cost of the outlet inner structure 32.

[0044] Further, refer to Figures 5 to 10 The return air assembly 4 includes a first return air interlayer 426, a second return air interlayer 427 and a second return air duct 428. The second return air duct 428 is connected to the second return air outlet 425 and the second return air interlayer 427. The first return air outlet 424 is connected to the first return air interlayer 426. The first return air interlayer 426 and the second return air interlayer 427 are used to transport air from the return air outlets connected to each other. In the embodiment of the present invention, the inner structure 32 of the air outlet assembly 3 and the inner structure 42 of the return air assembly 4 have the same structure. Figures 5 to 8For example, the outlet air internal structure 32 and the return air internal structure 42 are arranged in mirror-image alignment at both ends of the central axis of the clothes drying drum 1. Since the outlet air internal structure 32 and the return air internal structure 42 are circular flat structures, the actual structures of the outlet air internal structure 32 and the return air internal structure 42 are identical. The return air internal structure 42 is also provided with a first return air guide plate 421, a second return air guide plate 422, and a third return air guide plate 423. The first return air inlet 424 and the second return air inlet 425 are provided on the first return air guide plate 421. The first return air guide plate 421, the second return air guide plate 422, and the third return air guide plate 423 are respectively provided with a first return air interlayer 426 and a second return air interlayer 427. The second return air duct 428 connects the second return air interlayer 427 and the second return air inlet 425. The first return air interlayer 426 and the second return air interlayer 427 guide the airflow passing through the first clothes drying chamber 11 and the second clothes drying chamber 12 into the return air path, so as to be transported to the drying and dehumidifying module 71 to achieve circulation.

[0045] In one embodiment, referring to Figures 5 to 10 The air outlet assembly 3 also includes an outer air outlet structure 33, which is disposed outside the inner air outlet structure 32 along the axis of the central axis. A first cavity 333 is defined on a surface of the outer air outlet structure 33 proximate to the inner air outlet structure 32, and is recessed outward along the axis of the central axis. The inner air outlet structure 32 is rotatably disposed within the first cavity 333 along the axis of the central axis. The outer air outlet structure 33 is located outside the inner air outlet structure 32 and is disposed outside the inner air outlet structure 32 along the axis of the dryer. A first cavity 333 is defined on a surface of the outer air outlet structure 33 proximate to the inner air outlet structure 32, and is recessed outward along the axis of the central axis. The inner air outlet structure 32 is disposed within the first cavity 333, and the outer air outlet structure 33 encases the inner air outlet structure 32. The outer air outlet structure 33 supports the inner air outlet structure 32 and guides airflow into the inner air outlet structure 32. In order to enable the air outlet inner structure 32 to rotate with the drying drum 1 so as to synchronize the supply of drying airflow to the first drying chamber 11 and the second drying chamber 12, the air outlet inner structure 32 is configured to be circular and flat. On the circular and flat air outlet inner structure 32, the first air outlet guide plate 321, the second air outlet guide plate 322, and the third air outlet guide plate 323 are circular plates, connected by a structure passing through the center. At this time, the first air outlet interlayer 326 sandwiched between the first air outlet guide plate 321 and the second air outlet guide plate 322 is not blocked by any structure along the radial direction of the central axis. The shape of the first cavity 333 matches the air outlet inner structure 32. The space in the first cavity 333 provides the necessary accommodation space, allowing the air outlet inner structure 32 to rotate freely without interfering with other components.

[0046] In one embodiment, referring to Figures 5 to 10The air outlet outer structure 33 further comprises a first air outlet channel 331 and a second air outlet channel 332, the first air outlet channel 331 being in communication with the first air outlet layer 326, and the second air outlet channel 332 being in communication with the second air outlet layer 327, the first air outlet channel 331 being used for conveying the air flow blown by the first air blower, and the second air outlet channel 332 being used for conveying the air flow blown by the second air blower. Since the layered first air outlet channel 331 and the second air outlet channel 332 are arranged on the air outlet outer structure 33 in cooperation with the first air outlet layer 326 and the second air outlet layer 327, when the air outlet inner structure 32 rotates along the central axis, the first air outlet channel 331 and the second air outlet channel 332 arranged on the air outlet outer structure 33 can be directly in communication with the first air outlet layer 326 and the second air outlet layer 327, thereby realizing uninterrupted supply of the drying air flow.

[0047] In an embodiment, with reference to Figures 5 to 11 The air return assembly 4 further comprises an air return outer structure 43, which is arranged outside the air return inner structure 42 along the axial direction of the central axis, and one side of the air return outer structure 43 is provided with a second cavity 433 recessed outward along the axial direction of the central axis, and the air return inner structure 42 is rotatably arranged in the second cavity 433 along the central axis. Similar to the air outlet assembly 3, in order to enable the air outlet inner structure 32 to rotate with the drying drum 1 so as to keep the supply of the drying air flow to the first drying cavity 11 and the second drying cavity 12 synchronized, the air return inner structure 42 is arranged in a circular flat shape. The air return outer structure 43 is provided with the second cavity 433 for accommodating the air return inner structure 42, the second cavity 433 is shaped to cooperate with the air return inner structure 42, and the space of the second cavity 433 provides the necessary accommodation position, enabling the air return inner structure 42 to rotate freely without interfering with other components.

[0048] Further, the return air outer structure 43 further comprises a first return air duct 431 and a second return air duct 432, the first return air duct 431 is in communication with the first return air layer 426, the second return air duct 432 is in communication with the second return air layer 427, the first return air duct 431 and the second return air duct 432 are used to send air flow to the drying and dehumidifying module. The return air outer structure 43 is supported by the return air end frame 73 and connected with the return air pipeline 74. Since the layered first return air duct 431 and the second return air duct 432 are arranged on the return air outer structure 43 in cooperation with the first return air layer 426 and the second return air layer 427, when the return air inner structure 42 rotates along the central axis, the first return air duct 431 and the second return air duct 432 arranged on the return air outer structure 43 can be directly in communication with the first return air layer 426 and the second return air layer 427, realizing uninterrupted supply of drying air flow to the drying and dehumidifying module 71. The rear end pipeline of the drying and dehumidifying module 71 is connected with the circulating fan 72, realizing circulation.

[0049] Further, since the return air outer structure 43 is close to the circulating fan 72, in order to reduce the resistance of the drying air flow blown by the circulating fan 72, the connection between the first return air duct 431 and the second return air duct 432 is in a circular structure, and a smooth air flow guiding structure is arranged in the first return air duct 431 and the second return air duct 432, thereby reducing air resistance and air noise. The return air outer structure 43 is arranged close to the dryer door 82, after the drying air flow passes through the clothes in the drying cavity, the air flow speed decreases, in order to facilitate the arrangement of the return air outer structure 43, the interfaces of the first return air duct 431 and the second return air duct 432 are arranged in a flat shape, which can be a flat oval shape.

[0050] In an embodiment, referring to Figures 5 to 8 , the size of the first air outlet 324 and the first return air outlet 424 is larger than that of the second air outlet 325 and the second return air outlet 425. By the size difference, the types of clothes processed by the air flow of the first air outlet 324 and the return air outlet and the second air outlet 325 and the return air outlet can have different needs. The large-size first air outlet 324 and the return air outlet can ensure the efficient operation of the main air flow channel of the dryer, realizing efficient drying of conventional fabric clothes. The relatively smaller second air outlet 325 and the return air outlet can be used for drying clothes such as silk or other clothes with low fiber strength.

[0051] In an embodiment, referring to Figures 12 to 14, the space divider 2 is detachably arranged in the clothes drying drum 1. The air outlet assembly 3 also includes an air outlet baffle 31, and the air outlet baffle 31 is provided with a first D-shaped groove 311 near the center. The return air assembly 4 also includes a return air outlet baffle 41, and the return air outlet baffle 41 is provided with a second D-shaped groove 411 near the center. A main partition plate 21 and a secondary partition plate 22 are provided on the space divider 2, and the main partition plate 21 and the secondary partition plate 22 are connected. A rear interlocking protrusion 24 and a front interlocking protrusion 25 are provided at both ends of the main partition plate 21 along the central axis, wherein the rear interlocking protrusion 24 is detachably engaged in the first D-shaped groove 311, and the front interlocking protrusion 25 is detachably engaged in the second D-shaped groove 411. The secondary partition plate 22 can be folded and unfolded relative to the main partition plate 21 by a hinge for easy storage. The removable, foldable space divider 2 of this embodiment allows the dryer 1 to switch between zoned drying and regular drying, making it easier for users to use. Specifically, to ensure that the drying air fully contacts the clothes being dried, the air outlet shield 31 is evenly distributed with multiple diffusion holes. To prevent debris from the dried clothes from falling into the return air vent, the return air vent shield 41 is evenly distributed with multiple holes, allowing airflow to pass while minimizing the passage of debris. For ease of maintenance, the return air vent shield 41 is detachably mounted to the return air end frame 73.

[0052] Furthermore, to further enhance the support strength of the space divider 2 on the air outlet shield 31 and the return air vent shield 41, an annular groove 312 is provided on the air outlet shield 31. A first auxiliary protrusion 26 and a second auxiliary protrusion 27 are provided on the side of the main and auxiliary partition panels 21 and 22 adjacent to the air outlet shield 31. When the space divider 2 is installed in the clothes dryer 1, the first and second auxiliary protrusions 26 and 27 engage with the annular groove 312, providing the space divider 2 with more support points on the air outlet shield 31 and ensuring a more stable installation. Furthermore, the first and second auxiliary protrusions 26 and 27 can slide within the annular groove 312, facilitating the folding, storage, and alignment of the main and auxiliary partition panels 21 and 22.

[0053] In addition, the dryer of the embodiment of the present invention is also equipped with an intelligent temperature control system, which can adjust the temperature and wind speed according to the real-time data feedback from the humidity sensor to ensure that the drying time of the clothes in each drying chamber is balanced, thereby achieving energy-saving and efficient drying process.
